Problems solved by technology

Now other similar atomizing core nickel paste products mainly use nickel-chromium alloy powder as the main conductive material. This nickel-chromium alloy powder contains chromium, and it is easy to produce peculiar smell with a lot of e-liquid under high temperature heating state, resulting in poor taste, and electronic smoke The metal sintering temperature of the chemical core is relatively high, which requires high sintering process for large-scale industrial production
The width of the circuit line diameter after printing and sintering of this kind of paste is basically 0.3-0.5 mm, and the thixotropy is poor during the printing process, and the height is only 80-100 microns, and it is prone to problems such as virtual printing and disconnection. Small volume of suction mist

Abstract

The invention discloses nickel paste for an electronic cigarette atomizing core and a preparing method thereof. The paste is suitable for various porous ceramic atomizing cores, and is particularly suitable for porous silicon oxide ceramics. The paste comprises, by mass percent, 60 to 80% of nickel powder, 1 to 10% of hydrogenated titanium powder, 3 to 16% of glass powder and 8 to 30% of an organic carrier. Compared with an existing atomizing core nickel paste technology, the electronic cigarette atomizing core nickel paste has the ideal thixotropy, a fine line with the quite good high-width ratio can be continuously printed, virtual printing, line breaking and other problems cannot appear, low metallization sintering temperature is achieved, no lead or chromium or other poisonous metal iscontained in a component, the need for a large-scale industrial production sintering process is low, after cigarette loading, continuous suction atomization amount is large, the paste can be matchedwith various tobacco tar, the reduction degree of tobacco tar essence is high, in the atomizing process, no peculiar smell is generated, and taste is good.

Description

technical field [0001] The invention relates to the technical field of electronic smog cores, in particular to a nickel paste for electronic smog cores and a preparation method thereof. Background technique [0002] With the development of the electronic cigarette industry, the design of various electronic cigarette components is also approaching maturity. Among them, the technology of the electronic cigarette atomizing sheet of the metallized porous ceramic atomizing core is also becoming more and more advanced with the development requirements of the industry. It's getting finer. The heating condition of the matching of the atomizing core and the e-liquid, and the reduction of the essence of the matching of the atomizing core and the e-liquid are getting higher and higher. A metal circuit with a better line aspect ratio and good continuity has become one of the new technical development requirements. Now other similar atomizing core nickel paste products mainly use nicke...
